FEED-GRINDER.

SPECIFICATION forming part of Letters Patent No. 359,788, dated March 22, 1887.

Application filed June 3, 1886. Serial No. 204,023. (No model.)

To aZZ 10710771: it may concern:

Be it known that we, ISAAC J AY and JAMES C. JAY, both of Arapahoe, in the county of Furnas and State of Nebraska, have invented a new and useful Improvement in FeedGrinders, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of our improved feed'grinder shown as applied to a windmill, and the hopper being shown in section. Fig. 2 is a front elevation of the same, the hopper and its supporting-frame being removed. Fig. 3 is a sectional plan view of the same, taken through the line a: :0, Fig. 2.

The object of this invention is to provide feed-grinders constructed in such a manner that they can be readily adjusted to grind different kinds of grain, and which shallbe simple in construction and effective and reliable in operation.

The invention consists in the construction and combination of various parts of the feed grinder, as will be hereinafter fully described and claimed.

.Ve will describe our invention as being c011- nected with and operated by a windmill pitman, but do not li mit ourselves to that arrangement, as it can be driven by any suitable power.

A represents the frame of an ordinary windmill, the operating mechanism of which is not shown, as there is nothing new in its construc tion and operation.

Bis the pitnian of the windmill,which, in the drawings, is represented as working a pump, 0, but which can be connected with any de' sired machinery.

D is a walkingbeam, which is pivoted centrally to a post, 1* the frame A, or other suitable support. One end of the walking-beam D is connected with the pitman B, so that the said beam will be vibrated by the reciprocating movement of the said pitman. With the other end of the walking-beam D is connected the upper end of a pitinau, F, the lower end of which is pivoted to a plate, G, which moves up and down in guides in the frame H of the feedgrinder. The plate G is dressed orburred upon its forward side to operate upon the grain.

To the frame II, in front of the plate G, is journaled a cylinder, I, the face of which is dressed or burred to operate upon the grain. The face of the cylinder I is preferably dressed in three sections, the dressings of the three sections being of different degrees of fineness, to adapt the said cylinder to be adjusted to operate upon different kinds of grain. The journals of the cylinder I project, and to them are secured, by set-screws or other suitable means, crank-arms J, to which are pivoted the-lower ends of two pitmen, K. The upper ends of the pitmen K are pivoted to the ends of a cross-bar, L, attached to the walking-beam D, at a little distance from its end, so that the cylinder I will be rocked and the plate G moved up and down by the same movement of the said walking-beam D. Several holes are formed through the crank-arms J, to receive the pivot'pins of the pitmen K, so that the said pitmen can be readily adjusted to give a slow movement or a longer and quicker movement to the working-surface of the cylinder I, as the character of the work to be done may require. \Vith this construction, by loosening the cranks J the cylinder I can be adjusted to bring any desired section of its face into working position as the kind of grain to be ground may require.

The grinding-plate G is held forward toward the grinding-cylinder I by a roller, M, journaled in bearings N, which slide in horizontal slots in the frame H, and are held forward by spiral springs O, placed in the outer ends of the said slots, so that the grinding-plateG can move back should a nail, stone, or other hard substance come between it and the cylinder I, and will return to its place as soon as the said substance has passed.

The grain is fed into the space between the plate G and the cylinder I from a hopper, 1?,

supported upon a frame, Q, in front of the frame H.

Having thus full y described our invention, we claim as new and desire to secure byLetters Patent- 1. In a feed-grinder, the combination, with grindingeylinder I, aud t-he cranks J, of the the frame H, and the hopper P and its snppitmen F and K, the walking-beam D, and the port, of the reciprocating grinding-plate G, windmill-pitnnan B, substantially as herein the rocking grinding-cylinder I, the cranks J, shown and described, whereby the said feed- I 5 5 and a driving mechanism, substantially as grinder will be driven from the said Windmillherein shown and described, whereby the grain pitni'an, as set forth.

will be ground as it passes between the said ISAAC J AY; plate and cylinder, as set forth. JAMES C. JAY. 4 2. In a feed-grinder, the combination, with Vitnesses:
